Is crop N demand more closely related to dry matter accumulation or leaf area expansion during vegetative growth?

The critical crop nitrogen uptake is defined as the minimum nitrogen uptake necessary to achieve maximum biomass accumulation ( W). Across a range of crops, the critical N uptake is related to W by a power function with a coefficient less than unity that suggests crop N uptake is co-regulated by bot...
